Intel Core i7 3770K Ivy Bridge Linux Performance

Phoronix: Intel Core i7 3770K Ivy Bridge Linux Performance

Intel is finally announcing the first Ivy Bridge processors this morning. I have been extensively testing out the Intel Core i7 3770K, the current high-end Ivy Bridge processor, for the past few weeks under Ubuntu Linux. I have been extremely pleased with the Intel Core i7 Ivy Bridge processor under Linux with its phenomenal performance, power efficiency, and new features. This article is the first of many looking at the Linux performance of the new Intel Ivy Bridge processors.

What's up with all the Intel marketing slides (4 pages or so!), and why so much praise in this article? It's just a CPU, of course it's going to work well with Linux. And for most people modern CPUs have reached levels of performance that they don't really care about that anymore.

wow I never realized bulldozer was so good just goes to show you windows and application code is just optimized for intel. Bulldozer was within usually 30% of ivy ridge with march native, pile driver is supposed to be a 25% improvement closing the gap significantly. Coupled with better graphics I'd say AMD is killing intel (at least on source linux distros) I can't wait to get a trinity notebook and install gentoo

The selection of cpus to compare just miss one: i7-2600K or better i7-2700K (or i7-2600K @ i7-2700K clock speed). When you compare against i7-2700K it would be a 4% gain and against i7-2600 about 10%. It is not really good when you compare only against i5-2500K as that cpu has got no HT enabled. K cpus should be really easy to OC, other cpus can only raise the turbo multis +4 and a bit bclk. I would like to benchmark my i7-3770S but my board died - all i did was changing the boot order. (It was running at stock speeds, nothing oc.) One other aspect: the power usage was only tested together with a dedicated gfx card, that should be tested without for all cpus with integrated gfx core as well. Btw. it is also possible to OC the graphics core, my i7-3770S was set at 1150 by default, 1350 was possible without extra voltage, 1450 with 0.2v more. max clocks for my cpu have been 105.2*40 (40 only used for 3-1 core at full speed) without extra voltage, with 0.2v more i could use the full 105.2*43 (still only 39 for 4 cores the same time). But my cpu cooler was not good enough for permanent oc with extra voltage. One interesting aspect is when you set just the turbo modes for 4,3 and 2 cores active to the maximum you gain already a bit speed, but that resulted in +10C more heat (on full load) with my AC Freezer 7 Pro v2. So better use something bigger
